E. HALL COVEL, OF NEW YORK,

HYDROCARBON-VAPOR APPARATUS.

T 0 all whom it may concern:

Beit known that I, E. HALL CovEL, of the city of New York, in the countyand State of New York, have invented certain new and useful Improvementson Apparatus for Charging Atmospheric Air with the Vapor ofHydrocarbons; and I do hereby declare the following to be a full andexact description of the'same, reference being had to the accompanyingdrawings and to the marks and letters thereon.

In the construction of an apparatus for the purposes here named it isvery important that ample provision should be made for having itair-tight. So valuable has this provision been held that it has inducedmost individuals to believe that the apparatus could only be constructedof entirely rigid parts incapable of being separated from each otherexcept by mechanical means. When so constructed if any one part of theapparatusgets out of order great delay and inconvenience occur inrepairing it, and in case the apparatus should be found of less capacitythan desirable, it is necessary to replace it by one of more capacity;and, again, the apparatus has, no provisions for easy supplying it withmaterial when in use or for reaching its interior for cleaning or forother objects.

My invention is designed to overcome the several objections hereenumerated, and it consists in constructing the apparatus of severalpieces joined together by such means as allow of the various parts beingdetached, and of its capacity being diminished or increased, and when inuse of being supplied and examined interiorly without interrupting ordisturbing its functions.

Of the two views shown by the drawings forming part of thisspecification, Figure l is that of a transverse section in which thefeeding tubes are in line, and Fig. 2 a like section at right angles tothe first.

(a) indicates the shell or exterior plates of the apparatus; (6) the ansor chambers for the hydro-carbons; $2) the pipes or tubes for supplyingthese pans or chambers; (cl) the tubes for letting out the contents ofthe chambers or for examining the interior; (e) the inlets for theatmospheric air, which, as shown, are made up of perforated platescovering holes through the plates of the pans and top plate of theapparatus;

(f) the outlets for the charged air, also having perforated plates; and(g) indicates a reducing chamber, placed in the upper pan and below thetube which conducts the hydro-carbureted air to the burner or burnerpipe.

It will be perceived that the pans or chambers, as also the top-plate ofthe apparatus, are connected to the sides by a lockjoint, the edges ofthe pans and plate being turned downward and fitting into a groove orrecess formed by a flange or strip on the sides of the shell or exteriorplates of; the apparatus. By putting a resinous or other cement or analloy of metal fusible only at such temperature as may be deemeddesirable into the groove or recess, a perfectly tight joint will beformed and the apparatus become in every respect as useful as if thedifferent parts of it were rigidly united by mechanical means, while,whenever it may be necessary for any purpose to separate the parts ofthe apparatus, exposure of it to that degree of heat which will softenthe cement or alloy will allow of the taking apart of the entireapparatus. Under this construction the number of chambers or pans mayreadily be increased or diminished and the amount of surface for thehydrocarbon be enlarged or contracted without removal of any one of thechambers, as each chamber or pan may be subdivided into as few or asmany compartments as circumstances may require or demand. It will, also,be noticed that each pipe for conveyingthe material to the pan orchamber being independent of the others allows of the passing of thematerial into any one of the chambers, even during the time when theapparatus is in active operation, without the least inconvenience orapprehension of accident therefrom, as, also, the outlet pipes of thepans or chambers allow of the escape of any excess and of theexamination of the interior. p

The chamber (9) is specially designed for the admission of atmosphericair into it and for the more perfect union and commingling of fresh airwith that charged at a point away from .the burner, instead. of in theburner as has heretofore been practiced, whenever the air has happenedto have become too heavily or richly charged with the vapor of thehydro-carbon.

This apparatus is designed to be used in all cases Where air is to becharged for illumination, Whatever may be the articles used for yieldingthe vapor, by passing the air over the surface of the hydro-carbon; andit can be constructed of any of the materials ordinarily used for thatclass of apparatus and of such dimensions and formas may be regardedmost desirable. It can readily be constructed of cast-iron entirely orin part only. When constructed of cast iron the recesses or grooves forthe cement or alloy and the flanged edges of the pans or chambers can bea part of Whole casting,

Having thus fully set out the construction and operation of myinventionwhat I secure by Let- 'one of the chambers or to let outmaterial and to examine :the interior; While the apparatus is inoperation and the process of charging going 011538 herein set forth.
